Renting in Brooklyn: brownstones, basements, and what to check first
Brooklyn has every kind of NYC housing: rent-stabilized prewars, owner-occupied brownstones, new-build towers, and an informal market of converted cellars. Which one you’re in decides your rights. This guide shows how to tell before you sign.

The short answer
Three checks protect a Brooklyn renter more than any negotiation: (1) confirm the unit is legal, since a cellar apartment or an extra unit beyond the certificate of occupancy can be uninhabitable by definition and very hard to enforce rights in; (2) pull the DHCR rent history, since prewar buildings of six or more units are often rent-stabilized, with renewal rights and capped increases the listing won’t mention; and (3) run the standard New York math: one month deposit maximum, $20 application fee cap, $50-or-5% late fee limit, all layered under the city’s heat, hot-water, and bedbug rules.
First, know which Brooklyn you’re renting in
The same $2,800 gets you very different legal situations in Brooklyn: a rent-stabilized one-bed in a Crown Heights prewar, the garden floor of a Bed-Stuy brownstone whose owner lives upstairs, a unit in a Gowanus new-build with a tax-abatement stabilization rider, or a “cozy garden studio” that is, legally speaking, a cellar. Your rights come from what the building is on paper, not the neighborhood. Ten minutes with two public records (the certificate of occupancy and the DHCR rent history) tells you more than any broker will.
The basement apartment problem
Brooklyn has a lot of below-grade housing, and the legal line matters: a basement (at least half above curb level) can be a lawful dwelling if it’s in the certificate of occupancy with proper light, air, and egress; a cellar (more than half below) generally cannot. You keep your basic rights in an illegal unit, but everything practical gets harder. The owner can’t lawfully collect rent in some circumstances, insurance and repairs fall into a gray zone, and your leverage in any dispute is tied to a unit the city could order vacated. Since the basement-flooding deaths of Hurricane Ida, the city has paid closer attention. Check the certificate of occupancy before you fall in love with the garden.
The rent-stabilization check everyone skips
Brooklyn holds a large share of the city’s roughly one million stabilized units, which come with renewal rights and board-capped increases. They sit in ordinary buildings with ordinary listings. Six-plus units and built before 1974 is the classic profile; newer buildings with 421-a/485-x abatements also qualify. The check is free: request the unit’s rent history from DHCR. Two things it catches: units that are stabilized (leverage you didn’t know you had) and units deregulated on paper with rent jumps that don’t add up (evidence, if you ever need it).
Brownstone and small-landlord lease terms
Owner-occupied brownstones are Brooklyn’s small-landlord economy, with the same pattern as everywhere: inherited lease forms full of unenforceable terms.
“Occupancy restricted solely to the named Tenant. Landlord may access the unit via the interior stair as needed. Tenant shall pay a $150 monthly ‘house maintenance’ fee in addition to rent for shared utilities and cleaning.”
The occupancy clause loses to the Roommate Law (RPL § 235-f). Unlimited access “as needed” collides with your right to exclusive possession. Interior stair or not, this is your home, and entry needs a legitimate purpose and reasonable notice. The maintenance fee is at least disclosed, but add it to your real monthly cost when comparing listings, and get in writing exactly what it covers. Vague shared-utility arrangements are a common small-building dispute.
The money rules, Brooklyn edition
Add the $20 application-fee cap, the $50-or-5% late-fee limit with its 5-day grace period, and, since June 11, 2025, no fee to the landlord’s broker under the FARE Act (N.Y.C. Admin. Code § 20-699.21). The full statewide money rules are in our NY deposit guide; the first-timer fundamentals, including heat season and the bedbug disclosure form, are in the NYC first-apartment guide.
Questions renters ask
How can I tell if a basement apartment is legal?
The building’s certificate of occupancy (searchable on the Department of Buildings’ public site) has to show the space as a legal dwelling unit. Rough physical tells: a legal below-grade apartment must have real light, air, and egress. If the windows are slivers at ceiling height and the only exit runs through a boiler room, assume it’s a cellar conversion. An illegal unit is your problem too: evictions, deposit fights, and repair demands all get harder when the tenancy itself shouldn’t exist.
The listing says “net effective rent.” What am I actually paying?
Net effective means the advertised number averages in a concession, usually one or two free months on a longer lease. Your actual monthly check (the “gross” rent) is higher, and renewal negotiations start from the gross number, not the discounted average. Always ask for both figures in writing; the difference is often $150 a month or more.
My building has six units and was built in 1931. Am I stabilized?
Quite possibly. Six-plus units and pre-1974 construction is the classic stabilization profile, and Brooklyn has a lot of that stock. Request your rent history from DHCR (free, and you’re entitled to it). If the unit is stabilized, you get renewal rights and board-limited increases; if it was deregulated improperly, the history is the evidence. Landlords don’t volunteer this.
Can my landlord ban my partner from moving in?
No. New York’s Roommate Law permits your immediate family plus one additional occupant (and their dependent children) regardless of what the lease says, as long as you live there as your primary residence. The “single occupancy only” rider in small-landlord leases is unenforceable.
